Though if he said Manchester City is okay now he might be right because you can see what they have done recently but that doesn't mean they are the only one capable of wining this weekend because Arsenal also is capable. Difficulty is what it is for the two match but to prove some point Arsenal should win Manchester City so that Pep Guardiola will give Arteta a good regard that day, however since Rodri was on injury the first time they draw with Arsenal it will be even for the both team since saka may not going to play on this second match because of injury I presume but if so it will affect Arsenal more because Rodri is a defender while Saka is a striker.
